communication in space(sconce)

 hello everyone.

I will be talking about what we have been doing in science and answering some question about communication in space. first I will be answering the question about communication in space.

1.what are tree ways we communication and how do they work

Some people use phone calls when you call your friends the phone  converts

your voice into an electrical signal which gets transmitted via radio waves to the

nearest cell tower.

You can use a radio to communicate with people. It works by a transmitter sending and

getting electricity signals. The radio is sent outward by an antenna. a  receiver then picks

up the signal and translates it to the sounds heard through the radio.

Tv can be used to communicate. The camera turns the sound and picture. The tv

transmitter that sends the signal through the air then the receiver in  your tv at home picks it

up.

2.why cant you hear things in space

You can not hear in space because there is no air and your voice needs to vibration thowe

the air.

3.is radio communication  instant why or why not

It will not be instant because they will be so far away that it will take some time to reach

the spacecraft. Radio waves are very fast but its not instant radio waves actually move at

the speed of light.

4.what does this mean if we where going to go to mars from earth.

his means if nasa is trying to communicate it will take awhile to get a respond from the

other guys.  

and in sconce we had a challenge in the challenge we had to put a bucket over are

heads and a blind fold on and then we had to try to work straight and if we won we

got 5 buck and anyway until next time and I will make a blog on the challenge.
